domain will contain all integers but codomain will contain half of integers
So, it will be neither one to one and also not onto or surjective
0
what is the range of f(x) and g(x)?
0
how can it be unequal.. domain =(  infinity to +infinity)
range= (1 to infinity)
both cases.

Composition of functions
There exist 3 sets(A,B,C) and 2 functions f and g. g be a function from set A to set B f be a function from set B to set C then composition of both the functions is denoted by $f \circ g$ which exists. Then what is the necessary condition for the following 2 functions for the existence of $g \circ f$ a) Injection b) Surjection c) Bijection d) None of these

composition of function
Let f : A → B and g : B → C denote two functions. Consider the following two statements: S1 : If both f and g are injections then the composition function gof: A → C is an injection. S2 : If the function gof: A → C is surjection and g is an ... a)) and h(a) is onto then g must be onto, where ∀a, a ∈ A. Which of the above statements are valid? please give explanation

Function Composition
For gof to be onetoone, f must be onetoone but reverse is not true. Is the above statement correct? According to me both f and g must be onetoone for gof to be onetoone. I took below examples: (i) f is onetoone and g is onto Let A = {1 ... . Here, g(f(1)) and g(f(2)) both gives α which implies that gof is onetoone. Are above examples correct? If yes, please explain.
